Part codes for snom and Yealink phones including PSU to be removed

For some time now both snom and Yealink have adopted the more Green policy of supplying IP phones and PSUs separately and at ProVu we took it upon ourselves to maintain the old part codes that had previously included them. This has caused one or two issues and some confusion and so to keep things simple and clear we will be dropping the old part codes that had previously included the PSU.

We plan to delete the PSU included part codes from the 1st September 2014 and from then on our customers will need to order any PSU separately and in addition to the IP Phone when required.

Buying the PSU separately from the phone will not increase the price of purchase.

See table below of what you will need to order instead:

Old order code What to order instead
snom300-withPSU snom300 + Snom-psu
snom320-withPSU snom320 + Snom-psu
snom710-withPSU snom710 + Snom-psu
snom720-withPSU         snom720 + Snom-psu        
snom760-withPSU snom760 + Snom-psu
T19P T19PN + PSU-UK
T20P T20PN + PSU-UK
T22P T22PN + PSU-UK
T26P T26PN + PSU-UK
T28P T28PN + PSU-UK
T32G T32GN + PSU-UK-T3
T38G T38GN + PSU-UK-T3
T41P T41PN + PSU-UK
T42G T42GN + PSU-UK
T46G T46GN + PSU-UK-T3
T48G T48GN + PSU-UK-T3
VP530 VP530N + PSU-UK-VP

This change only affects snom and Yealink desktop phones. snom and Yealink DECT and conference phones will not be affected.

Yealink devices are not vulnerable to the Heartbleed bug

This advisory applies to all Yealink products using OpenSSL from version 1.0.1 to 1.01f. Notice supplied by Yealink UK on Weds 23rd June.

Heartbleed is a security bug in the open-source OpenSSL cryptography library, widely used to implement the Internet’s Transport Layer Security (TLS) protocol. This vulnerability results from a missing bounds check in the handling of the Transport Layer Security (TLS) heartbeat extension.

Through the vulnerability in OpenSSL versions from 1.0.1 to 1.0.1f, an attacker can capture memory from the host 64k at a time. The attacker can therefore possibly capture desired data such as the server’s private key, or a user’s password. This exploit is consistent with CVE: 2014-0160.

We have carefully inspected all versions of our products, and are pleased to announce that Yealink products are not affected by the Heartbleed OpenSSL vulnerability. We will update users if there are any changes in the future.

T19PN vs T21PN

We’ve recently had a few enquiries from resellers about the differences between the Yealink T19PN and the T21PN handsets.

gigaset pro logogigaset pro logo

The mains differences are as follows:
*The T19PN has one SIP account. The T21PN has two (it also has easy to use line keys on the side of the display).
*The T21PN has superior HD audio components, the T19PN doesn’t.
*The T21PN has LDAP directory support, the T19PN doesn’t.

Apart from that, and the colour of the LCD support, everything else is the same.

How to: Connect a Plantronics CS540 with a Yealink Phone

This is a step-by-step guide of how to successfully connect a Plantronics CS540 to a Yealink SIP phone (Compatible with T26P, T28P, T38G).

You should have:
– Plantronics CS540 Headset
– Yealink Handset with EHS capabilities
– Yealink EHS36 adapter.

(For a full list of headset and phone compatibility please view our headset compatibility chart)

The image below shows the contents of each box that will be required for this setup. They have been labelled for ease of idenitification and grouped according to which box you will find them in -see the key below.

Green – Yealink T38G Box
Yellow – Yealink EHS36 Box
Red – Plantronics CS540 Box

Step 1:
Once you have the correct parts ready, the next step is to connect the 3.5mm cable from the Plantronics base unit, to the EHS36 box. You can’t really go wrong here as they will only fit into one slot on each unit, but the picture below highlights where to connect them.

Step 2:
Connect the RJ12 cable from the EHS36 box to the EXT port on the back of the T38G. This port should be clearly labelled on the phone. See the picture below for illustration.

Step 3:
Connect the Plantronics RJ11 cable from the base unit to the Headset port on the back of the T38G. This port is labelled with a small headset icon, it is located next to the Receiver port, please make sure these are put into the correct slots. Again, the picture below shows how they should be connected.

That’s it! Power up the phone and the Plantronics base if you have not done so already. If this is a new purchase please allow a short time for the headset to charge before use. To charge simply place it onto the base in the very obvious slot.

If you have any problems after following this guide, please email support@provu.co.uk with details of your issue and a member of the technical team will be happy to advise.

Yealink Remote Control features

In an automated environment, it can be useful to control things without having to physically interact with them.

I refer, of course, to having to exert my energy on reaching to dial a number on my phone. You might well save yourself these exertions on a daily basis, so you can thank me later.

Here’s an example of dialling a couple of pleasant fellows:

http://user:pass@10.10.11.100/cgi-bin/ConfigMa
nApp.com?number=118118

If you try this on a more recent firmware, you may find that it doesn’t appear to do anything. Confusing at first but it seems there was a firmware change made for security purposes (can’t complain at that but it would be nice if the phone gave a 403 response when it does fail though!)

You now need to tell the phone what IP addresses to trust. If you web browse onto the Phone>Features page, you can find a text box labeled along the lines of “Trusted Action URI Server List”. You need to enter the IP addresses that the phone expects to receive requests from, as a comma-seperated list eg. 10.10.11.200,10.10.11.201

The first time the phone receives a remote request from one of these addresses, the phone does prompt you on screen to allow or reject the request (sorry.. you need to press the buttons this time!). I haven’t seen any subsequent prompts to confirm my consent.

If you want, you can also trigger key presses remotely:

/cgi-bin/ConfigManApp.com?key=OK
/cgi-bin/ConfigManApp.com?key=1
/cgi-bin/ConfigManApp.com?key=2
/cgi-bin/ConfigManApp.com?key=3
/cgi-bin/ConfigManApp.com?key=CANCEL

Isn’t that just great? You can build this into your CRMs or whatever else you can think of.

If you don’t have a Yealink phone to hand, you can browse the range: http://www.provu.co.uk/yealink.html

Now go and have some fun!
